This invention relates to improvements in roongtiles,'and has for itsobject to provide a tile formed of cement which shall be light, strong,and impervious to moisture.

A The invention consists in the parts shown in the drawings, describedin the specilication, and pointed out inthe claims.

1n the drawings, Figure 1 is a plan view of the outer side or face ofoneof my improved tiles; Fig. 2, a Vertical section thereof in line A B ofFig; 1; Fig. 3, an edge viewlooking from theright side of Fig. 1; Fig.4, a plan View of the .under side lof said tile; Fig. 5, a horizontalsection in line C D of Fig. 1; Fig. 6, a section` in line E F of Fig. 1;Fig. 7, a plan of a series or number of rows of tiles made to conform tomy invention and iitted to interlock with each other; Fig. 8, a verticalsectionin line I K of Fig. 7; Fig. 9, asection of a series ofinterlocked tiles in line L` M of Fig,l 7; Fig. 10, a horizontal sectionin line G H of Fig. 7'. The tiles hereinafter described are made ofceinena'sand, and .water pr'gperly mixed to form a mortar which will dryin the open air Without the use ofarticial heat or a dryingroom, butneed onlyto' be ."placed under an open shed'tobe'protected from theweather.

Roong-tiles formed of this material have proved of superior quality vand are light, strong, and impervious to moisture and are of small costcompared with tiles or roof-covering made of other material having likedurabi'lity. Tiles made of this material must be so formed that theywill iit snugly and securely together, and by my improved form 'andconstruction of tile this is fully accomplished Without the employmentof nails,wire, or other separate vfastening devices, and a tile isproduced which will fully answer all required purposes. Y

, My improved tile, as clearlyV shown upon the outside section, edge,and under side in the rst four figures of the drawings, is molded to theform of a square plate 1, a number of which are placed in diagonal tiersor rows, as shown in Fig. 7, with thetwo lower lap edges 2 of each tilehaving a downwardly-projectingv bead 10, which rests above and upon thetwo upper lap edges 3 ofthe other or adjacent tiles next below it. Inorder to secure this lap-joint, the opposite horizontal corners of eachtile are cut off in parallel lines 4 of the diagonal length of the lapedges 2, and thus allow the tiles to abut solidly at their adjacentcorners one against theother.

The two upper lap edges 3 have a channel, I

V5, running parallel to the adjacent sides of thetilefrom.Y the lowerends of the cornerlines 4 of the tile until they meet at right angies atthe upper corner of the tile, and the said channels 5 arebounded on theoutside by a raised bead 6, which merges into an outer groove 7 atthevery edgeof the tile. The groove 7 is used as a mortar-groove andextends Afrom a short distance above the upper ends of the corner-lines4 to the apex of the tile and is easily reached from the inside to befilled or pointed vup'eith'er when the tiles` are laid or afterwardshould the joint require attention.

Upon theunder edge of the tile, asshown in Fig. 4, a'piocket or recess 8is formed beneath the .extended portion of the b ead' and between thelower end of the mortar-groove 7 and the horizontalcorner'rof the tileto receive each one of the sides and ends'of a retaining-nose 9, formedto project downwardly from the under side ot the tile, as willhereinafter appear.

A bead l0 is formed on the under side of the tiles to extend from thehorizontal corn ers parallel with the two lower sides until they meetabove the lower corner or point of the tile, the said bead l() being solocated that it will snugly Iit into the channels 5 upon the upper faceand lap edges 3 of the tile and serve as the principal means forinterlocking the tiles together.

A mortar-groove ll is formed at the edges of the parallel corner-linewhich abut against each other at the said horizontal corners and providea useful and conveniently-located means for holding the four meetingcorners of the tiles together.

The tiles rest upon purlins or small strips of wood secured to therafters of the roof and are each intel-locked with one of said purlinsby a hang-nose l2 at the under side of the apex or upper corner thereof,which extends below the said purlin, as clearly shown in Fig. S of thedrawings, and together with the retaining-nose 9 atthe lower part of thetile will securely hold the tile upon the roof, when they are made tointerlock with each other, as above described.

A hub 13, with star-points extending therefrom upon the under side ofthe tiles, comes directly over the purlins and maybe supported therebyand raised to insure tightlytilting Contact with the roof and with eachother besides serving to greatly reinforce the tiles.

I claim as my invention and desire to secure by Letters Patentl. A tilemade in the form of a square plate having its side corners cut away, twoupper lap edges having an inner channel and a raised head, and two lowerlap edges, each having a head to tit the said channels of the upper lapedges, a retaining-nose extending downwardly from the underside andlower corner of the tile and recesses adjoining the upper ends of thesaid corners to receive said retaining-nose, substantially as described.

il. A tile made in the form ot a square plate having its side cornerscut away and mortargrooves formed in the edge thereof; two upper lapedges having an inner channel, a raised bead and an outer mortar-groove,and two lower lap edges, each having a bead to iit the said channels ofthe upper lap edges, a retaining-nose extending downwardly from theunder side and lower corner of the tile and recesses adjoiningthe upperends of the side corners to receive said retaining-nose, substantiallyas described.

In testimony whereof I aflix my signature in presence ot' two witnesses.

GUSTAV SCIIULZE.
